Vacuum Tube Equaliser Amplifier

Astatic model EA-1


The Astatic model EA-1 equaliser amplifier is a two-stage amplifier using a dual triode 6SC7 tube and is designed to operate with Astatic models MI-1 and MI-2 magneto-induction pick-up cartridges.

Used with these cartridges, the output from the EA-1 is distortion free and the frequency response is adjustable.

Equaliser circuits are provided between the two amplifier sections to provide for compensation of the normal magneto induction output characteristics to result in substantially flat frequency response.
